>Description:
It's very hard to distinguish where local address and port ends and foreign address and port starts from sockstat output when using IPv6 addressess.
One space between is enough as I think.

>How-To-Repeat:
root:net{R}[125] sockstat$ sockstat -6
www      nginx      58211 9  tcp6   2a02:6b0:1:0:21a:92ff:fe80:f032:802a02:6b0:16:0:10cb:d0b0:7274:4cde:1145
.. and more such lines
>Fix:
Just add one space after local address and port. And get output like this:

root:net{R}[135] sockstat$ sockstat -6
www      nginx      58211 12 tcp6   2a02:6b0:1:0:21a:92ff:fe80:f032:80 2a02:6b0:16:0:10cb:d0b0:7274:4cde:1170
